Most public bathrooms are not pleasant places to be – but the shortlisted entries to America’s Best Restroom contest have a whiff of style about them.

There were ten loos from across the U.S. vying for the top spot, including colourful restaurant toilets in Chicago, a Doctor Who-themed Tardis loo in Brooklyn, New York, and urinals at a baseball stadium in Pennsylvania, which feature a hands-free, motion-sensor computer game.

The toilets at Minneapolis-St. Paul International Airport were revealed as the winner, with their twinkling mosaic wall tiles, soft mood lighting and well-placed nooks to rest luggage.

Alan Howell, the airport's senior architect, commenting on the recent accolade, said: 'The restroom is often the first place visited on arrival and the last stop for departing passengers, leaving a lingering impression of their destination.

'We are thrilled to be honored with this award for our efforts to improve the aesthetics of our restrooms and make the customer experience memorable.'

Minneapolis-St. Paul International Airport's bathroom won 40 per cent of the nearly 5,000 votes cast.

The Charmery, a Baltimore ice cream shop with an undersea-themed bathroom, was the runner-up with around 16 per cent of the vote.

Other restrooms to make the top ten included those at The Novel Neighbor bookstore in St. Louis, Missouri, the Safe House restaurant in Allentown, Pennsylvania and the Urban Ecology Center's Riverside Park in Milwaukee, Wisconsin.

All three were praised for their kooky design, with unusual wallpapers, secret entrance ways and eco-friendly flushing systems.
